Thanks to Circuit Breaker Sales' affiliation with the Group CBS network of electrical equipment suppliers, we have access to hard to find vacuum interrupters and parts, and can reverse engineer replacement parts as necessary using modern technology.

While many categories of electrical equipment were manufactured to more rugged standards in the past than they are today, material science and manufacturing technologies mean that today's vacuum interrupter are far superior to older models. We don't use older, unreliable pinch tube and solder designs. Our replacement vacuum interrupters are compact, offer increased interrupting capacity and current carrying capabilities, and will last longer than the original interrupter.

Let us upgrade your circuit protection and motor control systems through vacuum interrupter retrofits to extend the life of your critical equipment.

MAC-TS4 Vacuum Interrupter Predictive Test System

Circuit Breaker Sales provides the MAC-TS4 vacuum interrupter tester, the third generation test set using patented technology for determining the condition of vacuum interrupters in the field, shop or laboratory.

New Technology - Better Results: Not a simple Go/No-Go ac high potential test, Magnetron Atmospheric Condition (MAC) vacuum interrupter test equipment predicts the usable life of a vacuum interrupter.

If you're looking for a meaningful vacuum interrupter bottle test, take a look at the outstanding capabilities of the new vacuum bottle tester, the MAC-TS4, a third generation vacuum interrupter test set.

Until now, the accepted field service test for vacuum interrupters has been a simple Go/No-Go test performed with an AC high potential test. Today, testing with the Magnetic Atmospheric Condition (MAC) test sets can prevent unnecessary damage to your circuit breakers and contactors by predicting the usable life of the vacuum interrupter.

Utilizing the Penning Discharge Principal, the MAC-TS4 vacuum interrupter test set can easily determine the pressure inside a vacuum interrupter and; along with wear and number of operations, predict the usable life of the vacuum interrupters used in your circuit breakers and contactors. Until now, this type of testing could only be done at the assembly plant.

Vacuum Interrupter Testing - MAC-TS4

Magnetic Field Test Coils

Flexible magnetic field coils are available for testing vacuum interrupters while installed in switchgear and magnetic field coil test fixtures are available for testing when removed.

Our unique, patented flexible magnetic field test coil enables vacuum bottle interrupters to be tested in-place, while installed in your circuit breaker or contactor. The flexible magnetic field coil is available in various lengths to accommodate most applications, and is used in conjunction with the MAC-TS4 vacuum bottle - interrupter tester.

For testing of individual vacuum interrupters that have been removed from a circuit breaker or contactor, a magnetic field coil test fixture is used in conjunction with the MAC-TS4 vacuum interrupter test set. Magnetic field coils are available in various sizes to accommodate most vacuum interrupters.

Completely Self-Contained

Completely self-contained, the MAC-TS4 is provided with everything required to test your vacuum interrupters in the field, shop or lab. It incorporates high-voltage power supply, back-lit LCD display, and built-in thermal printer; and is furnished with a complete set of test leads.

Computer Interface and Windows®-Based Software Provide Additional Capability

USB connection and the included Windows®-based software allows technician to control operation of the MAC-TS4 with an external pc, download stored test results, and generate test reports.
